Is it possible to use NIO to process the stdout from a Process? I have it working with java.io, but this is something of an exercise to learn a bit more about NIO and to explore the possibility of performance improvements.

Basically I want to stream a large volume of text from stdout into a buffer as fast as possible without blocking, and then process the contents of that buffer later. The trouble is, I can't seem to figure out the right voodoo to make it work with NIO. This is where I am right now:

I have created an open source library that allows non-blocking I/O between java and your child processes. The library provides an event-driven callback model. It depends on the JNA library to use platform-specific native APIs, such as epoll on Linux, kqueue/kevent on MacOS X, or IO Completion Ports on Windows.
